Abstract

Abstract: : Purpose: We had described an intraoperative breakage of 25–gauge DORC vitreous cutter. The aim of this study is to measure the bending strength of vitreous cutter at the opening port. Methods: The vitreous cutters of 25–gauge (Alcon, Fort Worth, TX, or DORC International, Zuidland, The Netherlands) and 20–gauge (1500 cutter, Alcon, Fort Worth, TX) were pulled at the direction of 45 degrees direction as monitoring breakage of vitreous cutter at the opening port. The bending strength was measured in each cutter. Results: Maximal point–loads against bending by are 25.1 N in 25–gauge vitreous cutter (Alcon) and 10.4 N (DORC) and over 100 N in 20–gauge vitreous cutter (Alcon). Conclusions: 25–gauge vitreous cutters are fragile, thus, we should be careful for surgical complications related to their fragility.
